AFTERMARKET REPAIR SOLUTIONS
DELIVERING VALUE AND CONTINUOUS IMPROVEMENT TAILORED TO YOUR NEEDS
As the global wind industry grows, the aging of turbines becomes increasingly important to address. In particular, foundation-to-tower connections often go unchecked, even with regular maintenance.
Ostermark Grouting, a leader in foundation grouting and sealing, now offers an inspection service for turbines aged five years or more.
Our service includes on-site inspections, crack mapping, measurements, engineering analysis, and repair recommendations.
By maintaining and repairing foundations and base towers, we help prevent water damage, minimize tower movement, and reduce grout deterioration, ultimately extending a turbine’s operational life without costly grout injections.
THE PROCESS
Inspection
Ostermark Grouting specializes in proactive inspections on turbines. Our dedicated service includes detailed on-site examinations where our expert technicians utilize advanced techniques to identify voids,cracks or structural weaknesses, in the turbine foundations. Through these precise inspections, we aim to detect potential issues early, helping to prevent costly repairs and extend the operational life of your turbines..
Inspection Report
Following our detailed inspections, we provide a comprehensive service report that includes visual analyses and measurements with accompanying photographs, observations of rust and grout condition, and recorded data on tower movement. Should there be a need for repair, we will recommend tailored solutions. This report is crucial for proactive maintenance, ensuring your turbines operate safely and efficiently, thereby prolonging their lifespan.
IMPLEMENTATION
Injection Works
Over time, turbines can become unstable when gaps form beneath the foundation. Ostermark Grouting performs investigative endoscopy through core drilling to detect and assess these voids. Once measured, the core is flushed, and Y-MatTec G1000 grout is injected to fill the gaps, restoring structural integrity and ensuring long-term turbine stability.
Foundation Coating
Ostermark Grouting offers sealing with Triflex Towersafe, a liquid-based, permanently elastic waterproofing solution for wind turbine foundations. It protects against water intrusion, corrosion, and environmental wear, ensuring long-term durability while minimizing downtime. Suitable for temperatures as low as -5°C, it provides reliable protection in all conditions..
Repowering Grout Collar
Ostermark Grouting strengthens existing turbine foundations with a repowering grout collar. By placing a form around the foundation and filling it with high-strength grout, we enhance structural capacity, allowing for the installation of larger turbine towers. This method reinforces aging foundations efficiently, ensuring long-term stability for upgraded wind turbines.
Foundation Repair
Ostermark Grouting offers foundation repair services to restore and strengthen turbine foundations. Using hydro demolition, we safely remove damaged material before reapplying high-strength grout to reinforce critical connections. This process prevents further deterioration, ensuring long-term stability while minimizing downtime.
